Pros Resolution, sharpness per pixel, relatively low noise levels, superior color rendition, very good dynamic range, superior handling, improved menu system, improved lcd, spot-on focusing.
Cons Could use: even larger magnification of viewfinder (although this would make the camera even bigger), dedicated ML button, improved software, greater than +1 diopter adjustment for the farsighted.
Summary I have been a professional photographer for over 25 years, with over 14 years of digital experience.
I'm not sure what the previous reviewer was referring to about software and formatting. The Canon supplied software is included with the camera and updates are free. There is no Canon software for the system that I am aware of that needs to be purchased separately. And, all the software is released for both Windows and Mac.
As a happy EOS 1DsII owner, the 1DsIII is pretty much what I expected - an improvement in just about every conceivable area. There's nothing revolutionary about this camera, unless 21.1 megapixel for a full-frame camera rates that adjective, but I am looking for the consummate professional tool - not a revolution. And here, the 1DsIII delivers just what it should.
The files look better than some very good medium format backs I've used. Some of the current highest-end mf backs will best it in pure resolution, but for convenience, lens variety and ability, speed, handling, high ISO, and versatility in a package that delivers image quality very close to the best, it leaves those others in the dust for my work.
Not to sound too much like a fan-boy, I must note Canon's bewildering refusal to put a dedicated mirror lockup button on the the camera. Also, even at the expense of making a big camera a little larger, I'd like to see an even higher magnification of the viewfinder (now 86%, how about 95-100%?) and an increase in the diopter correction on the plus side, from the current limit of +1 to +2, for those of us older folks with farsightedness. Lastly, the software, especially DPP for converting raw files, could and should be greatly improved with much more control of color, gamma, brightness, and highlight and shadow detail in the raw mode. And how about including more lenses in the list of those that can be "corrected" with the "lens aberration" tool.
All-in-all, this camera is a terrific professional tool which should help its users make the most of their picture-making abilities.
Pros 21 megapixels, low noise, high quality images...
Summary Wow... I have to said this is one of the best!
Pros Huge image quality
Cons weight, cost!!!!
Summary Having used Canons for some years, including the 1DIII (with no focus issues) I didn't even bother opening the manual, which is unusual for me - I usually read them slowly end to end for each new camera as the added value is often hidden in the details!
Easy to use, but still heavy compared to a 5D, the added microadjustment and live view are two definate value additions (same as 1DIII).
No issues working with Windows machine - not sure what the other review was on about, maybe he needs to read the manual.
Earlier cameras (1DIIn) had both firewire and USB, which was confusing as some features would only work with the firewire connection. This one, along with the 1DIII has only USB, but has an new option of a wireless connection which mounts on the left hand side.
Overall, you need to go to MF to get any chance of better detail (and I don't mean Mamiya ZD) and that's lots more $$$$
When Sony (Nikon?) get up to speed with their 24mp sensor Canon might get a run for their money, but until then ...
Pros Beautiful camera
Cons Does the software work
Summary I purchase a camera only to find out that it is in the Apple format and I'm Windows.Have the store show you the software program.If I get on the manufacturer's site my camera is re flashed to another format was a problem for me.Some of the software functions have to be purchased after the camera purchase and the updates are not free.
